Type member: Bunyamwera virus

Contents

This is one of the four animal virus genera in the family Bunyaviridae. The N and NSs proteins are encoded from overlapping reading frames from the S segment which, at less than 1.1 kb, is smaller than those of any of the other genera in the family. The name is derived from the type member, originally isolated from Bunyamwera, in Uganda.

Translation of the RNAs produces a polymerase (RNA-L), a protein precursor which is cleaved into two glycoproteins and a non structural protein (RNA-M), and two proteins from RNA-S, the coat protein and a non-structural protein in an overlapping reading frame.
